SPECIFICATION forming part of Letters Patent No. 696,484, dated April 1, 1902. Application filed November '7, 1901. Serial No. 81,476. (No model.)

To [all whom it may concern.- lar engines the internal exhaust-passages of Be it known that I, JOHN PLAYER, of Chi which are smaller and more direct and which cage, in the county of Cook and State of Illido not permit of the reexpansion of the exnois, have invented a certain new and useful haust-steam in its passage from the valve to Improvement in Locomotive Cylinders, of the exhaust-orifice. 55 which improvement the following is a speci- The object of my invention is to providea fication. cylinder of the type referred to in which the My invention, while applicable to steamsteam may be exhausted at the ends of the engine cylinders of other forms, relates more distribution-valve without involving the ob- IO particularly to locomotive-cylinders of the jectionable results above stated and which 60 half-saddle typethat is to say, those that shall be desirably adaptable to application in are cast integral with one section or half of a locomotives ot' the various types now known saddle or bed-plate-upon which the smokein practice without involving complication box of the boiler is supported and through or increased cost in construction or maintethe intermediation of which itis connected to nance. 65 the engine-frames. The improvement claimed is hereinafter In locomotive-cylinders of the above type fully set forth. the steam and exhaust passages are formed In the accompanying drawings, Figure 1 is in the saddle-sections, and the eX'haust-pasa side view in elevation of a half-saddle locosage of each cylinder terminates in a single motive-cylinder 'embodying my invention; 70 opening in the top of the saddle-section of Fig. 2, aplan or top View of a pair of cylinsaid cylinder, the exhaust-pipe, which may ders connected in operative relation; Fig. 3, be either single or double, being secured to a vertical transverse section through the cylthe saddle-sections above their exhaust-openinders of Figs. 1 and 2, the right-hand half ings. In the case of cylinders whose distribeing taken on the line a a of Fig. 4E and the 75 bution-valves provide for internal admission left-hand half on the line I) b of said figure; by internal edges and exhaust by external Fig. 4, an inclined longitudinal section on the edges there occurs the overpassage of the line 0 c of Fig. 3, and Fig. 5 a partial transeXhaust-steam from one end of the cylinder verse section showing the application of an g through the exhaust-cavity to the otherend. exhaust-pipe. 8c This overpassage of the exhaust-steam tends My invention is herein exemplified as apto retard its emission from the blast or explied in a cylinder saddle-section 12, which haust nozzle by reason of its reexpansion in accords with those now in approved service the enlarged eXhaust-chamberduring its pasin the general particulars of being a casting sage from the distribution-valve to the blastof box or chambered form, having a steam- 85 orifice and necessitates a decrease in the area cylinder 12 on its lower end, at the outer porof the latter in order to maintain a desired tion thereof, a distribution-valve chest 12", degree of vacuum in the smoke-box of the adapted to receive a piston distributionlocomotive. A further result of this overvalve adjoining the cylinder and communi- 40 passage of the exhaust-steam is to muflie or eating therewith near each of its ends by a 90 deaden the sound which it .makes in its esport 12 and a bed or supporting plate 12, cape, the effect of which has been to prejucurved to fit the periphery of a locomotive dice enginemen and others against locomosmoke-box on its top. Asuitably-fianged vertives in which it occurs and to lead persons tical web 12, which abuts against a similar so prejudiced to the belief that the performweb 011 a counterpart casting, is formed on 5 ance of the engines is not fully satisfactory the inner side of the saddle-section, or that and to induce them to further reduce the which is farther from the cylinder, and the area of exhaust-orifices thereon in order to two saddle-sections are connected in the produce a sharper sound, harmonizing with erection of the locomotive in the ordinary or that which is made in the operation of simiin any suitable and preferred manner. Ioo

In the practice of my invention a steaminlet passage 13 is formed in the saddle-section, said passage leading from the top plate 12 (at which it is, as usual, open for connection to one of the steam-pipes) to the central portion of the distribution-valve chest 12. An independent exhaust-passage 14 is formed in each end of the saddle and leads from the adjacent open end of the distribution-valve chest 12 ,with whichit communicates directly and fully to an exhaust discharge-opening in the top plate 12. The discharge-openings of the two exhaust passages 14 are located closely adjacent one to the other and to the inner web of the saddle-section, so that when the two sections are connected for attachment to the engine-framesthe four dischargepassages may be inclosed by a single exhaustpipe casting 15, secured to the top plate 12. Itwill, of course, be understood that the openings in the saddle-section at the lower ends of the discharge-passages 14c are closed by suitable removable heads 01' caps after the distribution-valve and its stem have been inserted in the valve-chest 12 The particular form of exhaust-pipe employed does not in and of itself constitute an essential part of my present invention, and any known and suitable construction thereof may be applied in the discretion of those skilled in locomotive-building. The exhaustpipe 15 herein shown is provided with four openings in its base, corresponding in form and relative location with the four dischargeopenings of the connected saddle-sections, and may either terminate in a single blastopening at its top or in any other suitable blastrdischarge appliance. An exhaust-pipe of this construction is deemed by me to be preferable; but it will be obvious that one having either a single opening in its base, communicating with all four of the dischargeopenings, or two openings separated by a central partition, each of said openings communicating with the discharge-openings of one of the saddle-sections, is equally applicable.

I claim as my invention and desire to secure by Letters Patent 1. A locomotive-cylinder saddle-section in which are formed an upper bed-plate, a lower cylinder, a valve-chest communicating, by ports, with the ends of the cylinder, a steamsupply passage leading from the bed-plate to the central portion of the valve-chest, and exhaust-passages leading from the ends of the valve-chest to independent dischargeopenings in the bed-plate.

2. A locomotiye-cylinder saddle-section in which are formed an upper bed-plate, a vertical inner web for connection to a counterpart saddle-section, a cylinder located on the outer and lower portion of the section, a valvechest communicating, by ports, with the ends of the cylinder, a steam-supply passage leading from the bed-plate to the central portion of the valve-chest, and exhaust-passages leading from the ends of the valve-chest to independent discharge-openings in the bed-plate located adjacent one to the other and to the inner web.

3. The combination of two locomotive-cylinder saddle-sections, each having an upper bed-plate, a vertical inner web for connection to a counterpart saddle-section, a cylinder located on the outer and lower portion of the section, a valve-chest communicating, by ports, with the ends of the cylinder, a steamsupply passage leading from the bed-plate to the central portion of the valve-chest, and exhaust-passages leading from the ends of the valve chest to independent dischargeopenings in the bed-plate, located adjacent one to the other and to the inner web, and an exhaust-pipe connected to the saddle-sections and having four lower openings, each communicating with one of the exhaust-passage discharge-openings.
